Cooper Clinic Physician Fights Aging
with Diet and Exercise

It was 12 years ago that the Dr. Arno Jensen first invited me to the
Cooper Clinic in Dallas for testing. I was 50 and Arnie was 59. David Prokop
went with me to write an article about the exam for Muscle & Fitness.
Daveís piece, which appeared in the May 1989 issue, included a sidebar titled,
"Dr. Arno Jensen: Practicing What He Preaches." The sidebar
heading was a perfect fit. It was true then, and itís true now. (Editor:
Prokopís article, which includes the sidebar, is on our home page under
the title "Fit at 50.")

Arnie has been training hard, weights and aerobics, and watching his diet for
decades Ė and it shows. He always looks lean and fit. I donít know his
percent body fat, but itís clearly quite low. Heís held the Cooper Clinic
treadmill record for his age group three separate times -- his best time is a
phenomenal 32 minutes.

The Cooper Clinic, founded by Dr. Kenneth H. Cooper, is best known in the
area of aerobic exercise. As many readers know, Dr. Cooper coined the term aerobics.
Arnie Jensen, who was part owner of a Nautilus facility in Iowa before he came
to the Cooper Clinic, was largely responsible for introducing strength training
at the Cooper Aerobics Center. Thanks to Arnie, the Cooper Wellness Program now
includes strength training along with aerobics; their onsite Fitness Center now
includes a fabulous weight training area.

Arnie and his wife Joan also have a fully equipped gym at their ranch in East
Texas. When I visited with them at the ranch earlier this year, I had the
opportunity to see Arnie do a weight workout. He didnít tell me what body
parts he was going to train, and I kept waiting for him to stop -- I fully
expected him to stop at least three different times -- but he kept moving
quickly from exercise to exercise, until he had trained his whole body. He never
let up, putting maximum effort into each exercise. I didnít time it, but Iíd
guess that the session lasted about 30 minutes -- half an hour of high-intensity
effort without a pause! Believe me, I was impressed. It took tremendous drive
and stamina to do that workout. It would have killed most 30-year-olds, and for
a man 71 years old it was truly remarkable. Arnie does indeed practice what he
preaches.

partial squats; an old football injury prevents him from doing full squats.

Needless to say, I thought of Dr. Jensen immediately when I needed someone to
speak to the concerns many traditional doctors have about the more aggressive
branch of anti-aging medicine discussed in the excellent article by Dr. Dave
Chauvin, which was posted here on Sept. 1 (Article #53, "Anti-aging
Medicine: Wave of the Future, or Wrong Turn?"). Dr. Chauvinís
article and the one by Dr. Jensen which appears below provide an interesting
counterpoint: high tech versus the tried and true. They give anyone
serious about staying young and healthy as long as possible plenty to think
about. Enjoy.

Anti-aging Medicine and Hormonal
Supplementation

By Arno L. Jensen, M.D.

I appreciate the opportunity to express my views on anti-aging medicine and
hormonal supplementation.

I have been practicing medicine for 44 years. For the past 19 years, I have
been at the Cooper Clinic in Dallas, Texas. My current big interest in medicine
is wellness and fitness.

At the age of 40, while still in family practice, I experienced chest pains
while rushing into the hospital to deliver a baby, and decided from that point
forward to be very proactive as far as my own health is concerned. That
experience made me realize that my health is far and away my greatest asset.
Since that time, I have done extensive "research" on my own body,
trying different forms of aerobic and strength exercise and different dietary
programs. Now, 31 years later, I am convinced that I have definitely slowed my
aging; I have also been able to slow the decline of my testosterone and
growth hormone levels. I attribute much of this to a well balanced strength and
aerobic conditioning program along with good nutrition, adequate sleep, and
reasonable control of stress. At 71, Iím stronger in many areas than I was
when I was playing competitive sports in high school and college. This is
particularly true in the all-important core muscle exercises, such as squats and
deadlifts.

I have also been fortunate to avoid illness. Believe it or not, I have not
missed one day from work because of illness in the 44 years Iíve been
practicing medicine. I have also been able to avoid medications that often
produce unpleasant side effects. For example, it is well known that many anti-hypertensive
medications as well as antidepressants, diuretics and others have impotence as
one of their side effects.

I have been able to lose fat and add muscle with my exercise and dietary
program. For the last 15 years, I have been able to keep my body fat well below
15 percent, which we here at the Cooper Clinic consider to be in the athletic
range. I try to motivate all of my male and female patients to keep their
percent body fat in the athletic range, regardless of age. As I said, for males
this is 15 percent or less; for females itís 22 percent or less. In almost all
cases, I have found that this can be accomplished entirely with proper exercise
and smart eating.

Low body fat and added muscle mass are important because, as Evans and
Rosenberg documented in their landmark book Biomarkers [Editor:
see our products page], those who are lean and strong not only look younger
than their years, they are in fact younger. We see this every day here at the
Cooper Clinic. Everything else being equal, the stronger athlete is the better
athlete. And I believe we are all athletes to a certain degree.

Fitness comes from the quality of the workout, not quantity. This is true not
only for the strength portion of the workout, but also for the aerobic portion.
As suggested above, the key to strength training is to emphasize the large core
muscles of the body instead of spending a lot of time on the smaller muscles,
such as the biceps. If one does a good job strengthening the core muscles, the
smaller muscles will automatically grow and become stronger.

For best results, workouts should be relatively short and focused, which is another way
of saying high in quality. Overly long workouts, strength or aerobic, can cause
the testosterone in your blood to decline. You should be able to complete your
strength workouts in no more than 40 minutes. For aerobic workouts, 30 minutes
is about right; you can become amazingly fit and be in the upper five percent
level of aerobic fitness with good quality sessions lasting no longer than half
an hour.

We canít stop aging, but I am convinced that we can slow it down. In a
manner of speaking, one can narrow the aperture of the hourglass and slow the
fall of the sand. Our goal should be to have our health span equal our lifespan.
Too many of us linger on in poor health, while the ideal should be to stay
active and healthy for most of our years, and when the decline comes it should
be precipitous and short. In my experience, most of us can achieve this by
following a healthy lifestyle, without the aid of hormonal supplementation.

It has been so rewarding for me to see patients completely transform
themselves with an excellent, well balanced exercise program and optimal
nutrition. On the other hand, it is very frustrating to see people accelerate
their aging because they refused to practice a healthy lifestyle.

Without question, there is a drop in the level of hormones, such as human
growth hormone and testosterone, as we age. Usually, however, the reason for a
greater than normal decline remains unclear. Many things can be responsible.
Physical inactivity, diet, medications, smoking and excess alcohol use can all
be factors as well as genetics in causing an accelerated decline in hormone
levels.

For some people, there is a place for hormone supplementation, but
I have rarely found that to be the case in my practice. In fact, Iíll bet I
can count the cases on the fingers of one hand were I found that hormonal
supplementation was necessary. My concern is that too frequently hormone
supplementation is given without adequate screening and evaluation, and without
sufficient concern for the possible harmful side effects.

Some of the long-term side effects of growth hormone supplementation can be
high incidence of carpal tunnel syndrome, joint discomfort and possible blood
sugar problems. Testosterone supplementation can also produce dangerous side
effects, particularly if administered to men who have normal levels. If your
levels are normal and you add exogenous testosterone, you can stimulate or
accelerate prostate tumors, both benign and malignant. You can also suppress
natural testosterone production.

At this point in time, we simply donít know the long-term side effects of
hormone supplementation, especially for people with normal levels for their age.
I recognize that hormone supplementation is an area that should be explored;
we need bold practitioners who are willing to break new ground. But I worry
about the legal risk to physicians who prescribe hormone supplementation without
adequate evaluation and follow-up.

Based on my own case, my long clinical experience and the concerns expressed
above, I encourage my patients to rely on a well-balanced exercise program,
strength and endurance, along with a very healthy diet. For the vast majority of
people, this will give the benefits of hormonal supplementation therapy, without
the long-term risks and expense.
